Class ConcurrentThreadLocal<T>

java.lang.Object

io.perfmark.impl.ConcurrentThreadLocal<T>

public class ConcurrentThreadLocal<T>
extends java.lang.Object

A "thread local" variable that uses weak refs to track the thread to value mapping. This class is useful when ThreadLocal instances are inconvenient.

Like All classes in this package, this class is not API stable.
